Physiological performance of rice (Oryza sativa) genotypes under submergence stress in Odisha

Abstract

Complete submergence of low land rice crops during flash floods occurs in large areas of South-East Asia, when plants may be completely under water for up to 1-2 weeks resulting in an increase mortality of plants vis-à-vis low productivity of rice crops. The present experiment was conducted in Adaptive Research Station, Sakhigopal, Puri during kharif 2017 to screen out the rice genotypes for submergence adaptation traits under agro-climatic ecosystem of Odisha. The present study indicated that among the selected genotypes, Varsadhan, Hanseswari and Champa contributed highest yield.
